UTOMATIC SHEET WINDING AND MEASURING MACHINE.

Application led October 17, 1921. Serial No. 508,229.

To all whom it may concern.'

Be it known that l, HARRY. CUMFER, a citizen of the United States,residing at Chicago, in the county of Cookand State of Illinois, haveinvented certain new and useful Improvements in Automatic SheetVvlinding and Measuring Machines, of which the following is aspecification.

The invention relates toimprovements 1n automatic sheet winding andmeasuring machines.

One of the objects of the invention is the provision of a machine whichwill wind a constantly moving, elongated sheet into rolls; sever thesheet; discharge the wound rolls and wind other rolls successively inthe same manner, thus continuing to wind the continuously moving sheetinto separated rolls until the sheet is exhausted.

Another object of the invention is the provision of a machine which willmeasure the sheet, as it passes into the roll being wound, and actuatingmechanism, initiated by the measuring mechanism, to cut the 27 sheetinto definite predetermined uniform lengths, and position the mandrelmembers to receive the succeeding end of the sheet to continue thewinding operation.

Another object is to generally improve machines of this character.

Other, further and more specific objects and advantages of the inventionwill become readily apparent, to persons skilled in the art, from aconsideration of the following description when taken in conjunctionwith the accompanying drawings, wherein Fig. l is a .front elevation ofa machine embodying my invention.

ln all the views the same reference characters are employed to indicatesimilar parts.

In the art of making prepared rooting an elongated continuous sheet,usually a sheet of felt, is saturated with hot asphalt, and in thecourse of converting the sheet into a waterproof finished commercialroofing product it must undergo, successively, a number of operations. Y

The exigeneies in manufacture, arising from the peculiar character ofthe materials forming concomitant parts of the finished product. demandthat the sheet shall be continuously moved during the entire period whenit is being acted upon. When the sheet of roofing has been completed andsuiliciently' cooled, it is then wound into rolls of definite length,convenient for sale, storage and for shipment.

Much inconvenience has heretofore been occasioned bv the necessity forwinding the continuous sheet into rolls without stopping its movementand considerable loss to the tot . being automatically performed.

lln the particular embodiment chosen for disclosing minvention there aretwo shaftsu porting rame members 15, one oneach si e, properly held toether by suitable tie beams and 15". main driving shaft 16 islongitudinally supported in the frame members 15 and is provided on oneend with a `inion 17.

he geai` pinion 17,'v carried by the driving power shaft 16, is in meshwith a larger gear 18 which is secured to the shaft 19, and this largergear is in mesh with the pulley 21 which is rotatably supported on astub shaft 22. The gear wheel 21 is in mesh with a gear wheel 23 that issupported upon a sleeve 24 by a key 25 (see Fig. 9). Sleeve 24 isrotatable upon shaft 26, when not clutched thereto. Another gear wheel27 is secured to the sleeve 24 by the key 28 and secured to the sleeve24 by the same key is a clutch member 29 for cooperation with the clutchmember 30 which is axially movable along the shaft 26 and which isrotatably secured thereto by a spline and feather 31. The two clutchmembers, 29 and 30, are normally held in enga ment bya spring 32 that iscoiled about s aft 26 and held in place by a collar 33. The use andoperation of these clutch members will be hereinafter l more fullyexplained.

The gear wheel 27, which is carried on the sleeve 24 of the shaft 26, isin mesh with an other gear wheel 34 which drives the shaft 35 through africtional connecting impositive driving means 36. The frictionconnector 36 consists of a hub 37 to which the gear wheel 34 isrotatably secured by the key 38. 'llwo clamping members 39 and 40, ofthe connector, are yieldingly held in contact with the disc 42, by aseries of circumferentially spaced apart springs 41 that surround studbolts 43 which project from the member 39 loosely through the member 40to permit the latter to slide on the bolts. The disc 42 is secured to ahub 45 by bolts 46, and the hub is secured to the shaft 35 by a key 47.The reason for impositively driving Ithe shaft 35 will be hereinaftermore full explained.

'll e sha-.tt 35 carries on each of its ends a sprocket wheel 48,secured thereto by a key 49. Sprocket wheels 48 are each connectedrecrear by a-chain 50 with sprocket wheels 51, respectively. Sprocketwheels 51 are rotatably secured to the axially movable mandrel members52. There is a spline 53 in each of the mandrel members 52 and a feather54 in each of the sprocket wheels'51, so that when the mandrel members52` are axially moved, into the dotted line positions shown in Fig. -1,the sprocket wheels 51 need not, necessarily be moved with thereciprocating mandrel members. Fach of the mandrel members 52 hasbearing in a fixed sleeve 55, and axially and adjustably movable overthe bearing sleeve 55 is another sleeve 56 having a flange head 57.These heads 57 serve as guides for the sheet that is to be woundintorolls, 58, and the heads 57 may be axially adjusted along the mandrelmembers 52 to positions appropriate for the width of the sheetl and thelength fof the roll to be wound thereon.

Each of the mandrel members at its inner end 60 is provided with atransversely and axially extending slot 61 to receive the end of thesheet when the latter is about to be wound into aroll upon said mandrelmembers.

` Fixed to the outer ends of the mandrel members 52 is agrooved collar62 which carries a loose ring 63 in the groove, the ring havinglaterally projecting trunnions or pins 64. A lever 65 for axiallyreciprocating the mandrel members, one for each, is pivoted at its lowerend, as at 66, to a standard 67, and its upper end 68 is forked and eachprong'of the fork contains a slot 69 to receive the pins 64. To give thelevers 65 their lateral movement, as shown in dotted lines in Fig. 1,and for the purpose of moving the mandrel members 52 from the interiorof the roll, comp'osedof the sheet v,

wound upon the composite mandrel, each lever 65 is pivotally connectedto a link 70, as at ,71.

The mandrel members are reciprocated by the levers 65 and these leversare moved by the following described means:

The inner ends of the links 70 are pivotally connected to cranks 73which are on opposite sidesof the shaft 74 and normally inpositions'shown in Fig. 4. The shaft 74 has rotatable bearing instandards 75 that rise upwardly from a plate 76, secured to the beam15a. The shaft 74 carries a miter gear 77 which is in driving mesh witha gear 78 secured to the main driving shaft 26. `When the shaft 74 isrotated one complete revolution, the links 70 are moved outwardly by therotating cranks 73 and being pivotally connected to the arms 65 thelatter are moved out into the dotted line poL sitions shown clearly inFig. 1, thereby withdrawing the mandrelmembers 52 from lthe interior ofthe roll that has previously been coiled thereabout. This movementsource, the roll 81 is shown onl for illus-`v `trative purpose. 1npractice t e sheet is wound directly into rolls 58 coincidently with itsmanufacture. The sheet passes over idler roller 82 supported on theshaft 83 and then passes between the feed rolls; then between the roller84 and the rotating knife 20. AThe roller 84 is supported upon journals85 in vertically movable journal boxes 86, so that knife 20 may beseparated adjust-ably from the roller 84 in order that it may evenlycontact the confronting surface of the roller 84 at the time when it issevering the sheet. The rotatable member 87 carrying the knife 20 isprovided with shoulders88 against which the knife 20 is secured in fixedposition by a bar 89 held in place by cap screws 90. When the member 87is rotated about the time when the roll is finished, the knife 20 makeseven contact with the peripheral-surface of the roll 84, and thereby thesheet is severed. The boxes 86, at each end of the roll 84 and whichsupport the journals 85 of the roll 84, are'vertically movable at eachend of the roll by hand wheels 92 and the threaded rod 93. The boxes 86are movable in the guide 95 and the respective ends of the roll 84 maybe independently adjusted so that its surface may be brought intoalignment with the cutting edge of the knife 20. On one end of the roll84 is a gear wheel 96 which meshes with a gear wheel 97 on the shaft 19.The knife-bearing member 87, (Fig. 7) is extended into a bearing sleeve98, at one end, to which is secured a clutch member 99 for cooperationwith a clutch member 100 that is secured to the shaft 19 by key 101. Acoil spring 102 yieldingly holds the clutch members normally in contactand a key 103 rotatably connects the clutch member 99 to the sleeve 98,so that when the' shaft 19 is being rotated and the clutch members arein contact. as shown in Fig. 7, then by operation of the shaft 19`theknife 20 is rotated to sever the sheet 80. The spring 102 abutsvagainsta collar 104 which is loose on the sleeve 98.

The gear 97 which is on the shaft 19 is in mesh with the gear 105 (Fig.2)` and this gear is in mesh with another gear 106 on the lower sheetfeeding roll 107. The upper feed roll 108 carries a gear 109 which isdriven by the gear 106 so that the sheet 80 passing thru and between therolls 107 and 108 is thereby fed thru the machine. The upper roll 108 israised and lowered, with respect to the lower roll 107, by means of ahand wheel 110 which is connected to a shaft 111 and which rotates mitergears 112 that are in mesh with other miter gears 113 that rotate nuts,not shown, around the threaded, vertically disposed stem 114, the latterbeing secured inthe box 115 that supports the journals of the upper roll108.

Now, from the foregoing description, it will be seen that the sheet 80may be fed thru the machine and wound into rolls 58 and that the sheetmay be severed when the roll 58 has been completed.

The sheet measuring means, in cooperation with the feed rolls, initiatesthe sheet cutting operation as follows The lower feed roll 107 (Fig. 3)carries a gear wheel 116 which is in mesh with another gear wheel 117carried on the shaft 118, on which is secured a smaller gear wheel 119in mesh with a relatively' large gear wheel 120 and this latter gearwheel carries a pinion 121 in mesh with a measuring gear 122. Gear 122is secured on a shaft 122. The measuring gear 122 may be replaced byanother gear of smaller diameter when sheets of other lengths are to bewound into rolls 58.

The gear 122 carries a detent 123 and there are four locations, 124, atwhich, selectively or inclusively, these detents may be placed. If adetent be placed at 124, diametrically opposite A the detent 123, thenthe sheet wound into a roll would be half as lonor as when one detentonly is attached to the wheel 122. A smaller wheel in substitution forwheel 122 may be placed on vertically adjustable shaft 122' by raisingthe bearing until the' smaller wheel is in mesh with the pinion 121.

A lever 125 is pivoted, at 126, and on its extended end bears a roller127 which normally rides on the periphery of the measuring gear 122.This structure is shown more clearly in Fig. 5. The clutch membersl 99and 100 are connected by displacement of a vertically movable rod 128.Rod 128-car ries a collar 129 on its upper end and a spring 130 abutsagainst the collar to yieldingly hold the upper end 131 of the rodnormally in the groove of the clutch member 99. Bridging the groove 132of the clutch member 99 is a cam plate 133, shown more clearly in Fig.13, as associated with the clutch member 30, as indicated. in Fig. 5.The same sort of cam plate is provided for the clutch member 99, andwhen the tapered portion 134 is brought into contact with the upper end131 of the rod 128 the clutch member 99 is moved axially of the sleeve98, out of contact with the clutch member ioo to the arm125 of theliever 125.

10o, thus holding the Shan 1 9 and knife bearing roller 87 out ofdriving connect-ion with the rotating sleeve 98.

To displace the end 131 of the rod 128 there is shown, in Fig. 5, a dog135 pivoted at 136 The dog is provided with a nose 137 which normallyrests in the notch 138 made. in the rod 128. The dog 135 has anelongated end which is held yieldingly away from the lever member 125 bya spring 128 so that the nose 137 will yieldingly engage notch 138 ofthe rod 128. An adjusting screw 139 contacts the outer end of the dog135'. Now when the roller 127 onthe outer end of the lever 125 is raisedby the detent 123 the member 125? will be depressed and the dog 135 withits nose 137 engaging the slot 138 will cause the rod 128 to bedepressed against the resilient effect of the spring 130, therebywithdrawing the end 131. of the rod 128, out of the groove 132 on theclutch member, per'- mitting the clutchmembers to become drivinglyconnected by operation of the spring that surrounds the respectiveshaft. In Fig. 7 the clutch member 99 is thus brought intodrivingengagement with the clutch member 100 and therefore the shaft 19will rotatethe knife 20 on the knife carrier 87 one revolution, and theknife, coming in contact with the surface of the roll 84,

will sever the sheet that is at that time bebers 29 and 30 separated, inwhich event sleeve 24 (Fig. 9) will not rotate the shaft 26, but whenthe clutch member 30 is released, in the manner heretofore made clear.spring 32 will move it along the shaft 26 until nit makes drivingconnection with the member 28 and then the shaft 26 is rotated by thesleeve 24. The lower end of therod 140 (Fig. 6) is pivotally connectedto a link 143 which in turn is connected to a vibrating arm 144 as at145 and this arm is secured to a shaft 146. Secured to the same shaft isanother similar but shorterarm 147 lto which is pivoted a verticallyextending rod 148, at 149. An arm 150 is pivoted to a stationary portionof the machine frame at 151vand has its free end, 152, normally in thepath of a pin 153 which projects from a collar 154 extending from theknife-carrying member 87. This pin 153 maybe located on the collar 154at a position where it will operate the lever 152 at a predetermined isrotated that the clutch member 30 on thev shaft 26 is permitted tocontact the clutch member 28 and rotate the shaft.

The gear wheel 23 on the shaft 26 positively rotates the sleeve 24 andthe gear 27. The gear 27 positively rotates the gear wheel 34 whichis'secured` to the hub 37, but

the shaft 35 is impositively driven by the gear wheelv 34 thru africtional drive 36 so that if the shaft 35 be positively stopped thegear 34 will be permitted to rotate by the friction between the members39-40 and the member 42.

In order that the beginning end of the moving sheet shall make windingengagement with the mandrel members 52 it is convenient to have themandrel members 52 briefly stopped in their rotation, at proper periods,so that the end of the sheet will invariably enter the slots 61 made inthe confronting ends of the mandrel member 52.

The device shown in Fig. 14 is a means by which the shaft 35 ispositively stopped periodically so that the mandrel members will occupythe )ositions .shown in Fig. 1 with the slots in orizontal planes incondition for the sheet to enter the slots. Mounted on theintermittently rotatable shaft 26 is a cam 156 secured thereto by a key157 and arranged to depress aroller 158 on the end 159 of a. lever 160.The lever 160 is pivoted. at 161 and has a forwardly extending end 162which engages a shoulder 163 made in a cam 164, which is secured to theshaft 35 by a key 165. The cam 164`has another notch diametricallyopposite the notch 163. This notch is indicated by 166 and in turn willmake contact with the end 162 of the f lever 160. It is only necessaryto rotate the mandrel members one-half revolution to bring the slots 61into horizontal planes and shaft 35 rotates coextensively with themandrel members.

A spring 167 tends to yieldingly hold the end 162 of the lever 160normally in contact with the peripheral surface of the cam 164. Inoperation the shaft 26 is rotated only one revolution at uniform periodsof time and its movement is initiated by the operation of the measuringdevice heretofore described. The normal position of the lever 160 isshown in dotted lines in Fig. 14 Wherein'the end 162 of the lever 160 israised above the shoulders of the cam 164. This is accomplished when theflat ortion 170 of the cam 156 is immediately a ove the roller 168 asine-reati shown in dotted lines, and this is the normal position of theparts.

While the shaft 26 is being rotated and the flat portion 170 leavescontact with the roller 158 tlien the spring 167 will depress the end162 until it will rest behind one ot the shoulders 163, or 166 of the'cam 16%, and hold the shaft 35 stationary in exact position. The objectof this is to hold the man'- drel members stationary in the positionshown in Fig. 1 during their momentary dwell, so that the slots in themandrel members are properly presented for the entrance ot the oncomingsheet. As soon as the shaft 26 has made its complete revolution then theend 162 of the lever is raised into dotted line position and the shaft35, which controls the rotation of the mandrel members is released.During the time when the shaft C35 is (stopped, in the manner described,there is slipping engagement between the members of the transmissiondevice 36, between the member 42 which is secured to the shaft and -themembers 39 and 40 which are secured to the hub 3'?.

lt is now manifest that the diameter of the wheel 122 which carries thedetent determines the length of the sheet 80 to be wound into the 'rolls58, `and that it is positively driven by gearing rotated by the samesource of power which moves the sheet. lf detents 123 be placed in allof the notches 124, then the length of the sheet that will be Wound intorolls 58 will be one-fourth the length that it Ywould be it'. only onedetent were used and it' it is desirable a smaller wheel correspondingto the wheel 122 with a' single detent may replace the .wheel 122 byraising the bearing which carries the wheel, so that the smaller wheelwillreadily mesh with the pinion 121. It it is desirable to wind rollswith lengths one-halt of the exhibit shown then the second detent may beplaced diametrically opposite the location ot the detent 123 on thewheel. 122 so that the length of the sheet. to be wound is readilydetermined by the measuring device.

Briefly, a recapitulation of the operation mag be-stated as followsconstantly moving sheet to be wound into rolls is passed thru themachine. li'tpasses between feed rolls that keep the sheet continuallymoving and lwhich operate a train of gearing which moves an ultimatemember thereof a predetermined distance. rThe ultimate member initiatesa cutting'ol knife which severs the `sheet into predetermined lengths;each length is contained in a wound roll. rllhe sheet is wound upon twocoaxially arranged, slotted mandrel members which just subsequent to thesevering of the sheet are moved axially away :from each other towithdraw them from the roll and the finished roll is thus allowed todrop away from the machine. The mandrel members are then returned toroll-winding positions and J are stopped from rotating with the slots ina horizontal plane in which the sheet is then moving and for asuiiiciently long period to permit the endet the sheet to enter theslots, after which the mandrel members are again rotated to wind anotherroll and the operations are repeated,
